"I just peed on my daughter with a good friend... It's a bit disturbing," said Stilgar, after watching his daughter be ass-raped by a young sandworm with little resistance. I quote this moment as it perfectly epitomizes the atmosphere this game establishes.
Story/Writing: The story isn't the best. It's a Dune parody but everything occurs too quickly. By the time something happens, it's already over. The story also takes itself too seriously one moment then not seriously the next; the tonal whiplash is rough. Where the writing really falls apart is with the characters. They'll speak to you like you're a pariah one moment, then after two dialogue boxes they're worshiping you and fucking your brains out. One massive positive is that the "sex text" is executed perfectly. It's not too long, not too short, and actually enhances the scene.
Hentai: It's pretty good. Keep in mind, this game is incredibly short. You can speedrun it and get a sub 4 minutes. That said, the quantity of scenes (that are not reused scenes) is more than what should be expected for a game this short. The quality of scenes is nice as well; it's arousing and stylistically unique for a h-game (it has well-made Western-style artwork). My issue with the porn is that for quite a few of the girls it reuses the same exact animation in order to make it appear as though there are more scenes than there actually are. I'm of the mind that it's better to exclude this type of content and to not tease additional girls instead of giving a wide variety of girls with half-assed scenes. The other issue with the hentai is that the sex pacing, similar to the story pacing, is horrific. I want to make a note of one gleaming positive that is heavily biased by my preferences: This game features not one, but two short haired girls. My god is it glorious, even though the one girl is one of the aforementioned half-assed scene girls.
Gameplay: What gameplay? The management aspect is incredibly simple and has no significant grind or effort required, to the point where I question its inclusion. The "point and click" gameplay is also notably dead, with only a few uses here or there. As I said, "what gameplay." It's essentially just a visual novel with a bad story and some good porn.
tl;dr: The hentai is better than what you should expect from a 2016 flash h-game. For note, you can (and should - that's right I'm judging you during a review on a hentai game forum) turn the scat off. The story is lacking and so is the gameplay, and since the gameplay is lacking the story needed to shine, which it doesn't. All things said, it's worth playing.
